2777 :: [Newbie question] How to debug?

• Greglefox (orginal) [2017-02-01T07:47:50+01:00] view original

  Hi all

  I am learning Nim and looking to debug "seriously", i.e. out of echo and potentially considering threads.

  The environment is Windows 7 64bits with:

  Nim 0.16 ZIP release

  I found a quite good MinGW implementation that is updated on a regular basis: https://sourceforge.net/projects/mingw-w64/files/Toolchains%20targetting%20Win64/Personal%20Builds/mingw-builds/6.3.0/threads-posix/seh/

  VisualCode for the editing with

  Nim extension: https://marketplace.visualstudio.com/items?itemName=kosz78.nim

  Native Debug: https://marketplace.visualstudio.com/items?itemName=webfreak.debug

  I tried the following approaches: https://hookrace.net/blog/what-makes-nim-practical/#debugging-nim and https://forum.nim-lang.org/t/2061/2

  Using internal debugger (ENB) or regular GDB approach gives me plenty of pain: in both cases the debugger cannot refer to the right line in the code, that makes the debugging impossible. Also the names of the local variables are quite complicated to recognize / understand (sometimes I can guess)

  Any experience to share?

  Dunno, for me it always refers to the right line in the code, I use --debugger:native. Report a concrete bug please. Local variable names have a 0 appended if they don't come from some template instantiation. Reduced name mangling is being worked on though and should make it into 0.16.2.
